Problems solved by technology

Generally, harvested and processed in summer and autumn, dried or dried, the harvested corn whiskers are shriveled, less glossy, low in nutritional value, high in impurities, and degraded in use quality.
Due to the backwardness of production and processing methods, corn silk, which has health care and medicinal value, is a large amount of beneficial plant resources wasted

Embodiment 1

[0031] In this example, the excellent corn variety Ludan 981 was selected to produce high-quality and high-yield fresh corn silk in Yangling, Shaanxi. Specifically include the following steps:

[0032] The first step is to select an excellent corn variety Ludan 981 (National Examination Yu 2003011) (variety right number: CNA20000003.9) suitable for corn silk production. This variety has the characteristics of thick filaments, long filaments, high yield and good quality.

[0033] In the second step, Ludan 981 planted seeds in Yangling, Shaanxi. The selected maize variety Ludan 981 was planted at a row ratio of 2:5, 5 rows in the row ratio were sown on June 10, and 2 rows in the row ratio were sown on June 15. Since the maize varieties sown in Yangling in early June have flowering and pollination time in mid-August, when there is a lot of rain, the late sowing rows that provide pollen should be more appropriate to prevent cloudy rain from affecting pollination and reducing gra...

Embodiment 2

[0038] In this example, the excellent corn variety Ludan 981 was selected to produce high-quality and high-yield fresh corn silk in Sanya, Hainan Province. The product is less harmful by diseases and insect pests, clean and hygienic, less pesticide pollution, and low in harmful substances. Specifically include the following steps:

[0039] The first step is to select an excellent corn variety Ludan 981 (National Examination Yu 2003011) (variety right number: CNA20000003.9) suitable for corn silk production. This variety has the characteristics of thick filaments, long filaments, high yield and good quality.

[0040] In the second step, Ludan 981 was planted in Sanya, Hainan Province. The selected maize variety Ludan 981 was planted at a row ratio of 1:3, 3 rows in the row ratio were sown on November 5, and 1 row in the row ratio was sown on November 15. Since the corn varieties sown in early November in Sanya, Hainan, flower and pollinate in early January of the following ye...

Abstract

The invention relates to a manual bagging method of fresh corn silk. The method comprises the following steps: selecting the corn variety with large filament diameter, long filament length and high yield, periodically sowing the corn variety at a row ratio of 1:3 or 2:5, covering female ears with plastic bags or paper bags before the corn in the early-sowed corn rows begins to product silk but not produce bracteal leaf, fixing the plastic bags or paper bags on the corn ears by using pins or clips, removing the plastic bags or paper bags 5-10 days after the filament in the early-sowed corn rows begin to grow, and harvesting fresh corn silk. After the corn silk in the early-sowed corn rows is harvested, the male flowers in the late-sowed corn rows begin to spread pollen and thereby provide pollen for the early-sowed corn rows, so that the corn in the early-sowed corn rows can fruit normally after corn silk harvest without affecting the production of corn seeds. The method can yield high-quality fresh corn silk with less insect pest, hygiene, less pesticide pollution and low harmful substance content.

Description

technical field [0001] The invention belongs to the field of plant production methods, and relates to a production method of health food and Chinese medicinal materials, in particular to an artificial bagging production method of fresh corn silk. Background technique [0002] Corn silk (corn silk or stigma maydis), also known as dragon silk or stigma maydis in traditional Chinese medicine ("Southern Yunnan Materia Medica"), corn stamen ("Modern Practical Chinese Medicine"), stick hair "Hebei Medicinal Materials" and so on. It is the style and flower head of corn of the grass family Zea genus, also known as filament, and is one of the commonly used medicinal materials included in the "Standards of Medicinal Materials of the Ministry of Health of the People's Republic of China" (1985 edition one). Corn whiskers are often assembled into loose clusters, and the styles are long and thin filamentous or whisker-like, with a length of more than 30 cm and a diameter of about 0.2 mm t...
